Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing, in particular to a rotating bracket for an H-shaped steel workpiece. Background Art

[0002] At present, after shot blasting, H-shaped steel components need to be cleaned from the steel shot and dust attached to the surface of the components, especially the steel shot and dust in the densely populated parts, so as to keep the surface of the steel components clean and reuse the recycled steel shot. Due to the structural characteristics of H-shaped steel components, when cleaning H-shaped steel components, they must be turned over to complete the cleaning of steel shots.

[0003] The current flipping method in the production workshop is to use an inclined plate clamp to lift the flange plate on one side close to the center of gravity of the H-shaped steel member and flip the member to one side about 45°, so that the steel shots on the upper surface of the flange plate and the oblique lower surface of the web slide down by their own gravity, and then use an inclined plate clamp to lift the flange plate on the other side close to the center of gravity of the H-shaped steel member and flip the member to one side about 45°, so that the steel shots on the surface of the other side of the component slide down by their own gravity.

[0004] However, due to the large size and weight of the component, if the inclined plate clamp is unhooked due to improper operation or the plate teeth are not firmly clamped, the component will suddenly fall, and at the same time, it will cause an instantaneous upward impact on the crane, causing damage to the steel component and the crane. In addition, the continuous unhooking and lifting of the workpiece will affect the production efficiency, especially the personal safety of the operator, which may cause work-related injuries.
